Pancreatic adenocarcinoma may account for more than 80% of all pancreatic neoplasms. Occasionally, other rare tumors such as lymphoma, metastatic tumor, and solid pseudopapillary neoplasm can be considered in the differential diagnosis. We report the case of an 82-year-old man with a pancreatic solid mass. This case suggests that endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) with biopsy, that is, EUS-FNA is recommended in the differential diagnosis of the pancreatic solid mass apart from pancreatic adenocarcinoma. In particular, the histologic core obtained by EUS-guided biopsy is helpful for the immunostaining of molecular markers to confirm the final diagnosis.
